The instant invention refers to nanosystems comprising nanocomposites for adsorption or support of natural extracts; a process for the preparation thereof; formulations containing thereof, as well as a nanomaterial that adsorbs one or more essential oils in its surface. Specially, one object of the invention is the encapsulation of natural extracts, i.e., essential oils and/or natural pure bioactive compounds and optionally terpenoid, sesquiterpenoid, diterpenoid, sesterterpenoid, triterpenoid, carotenoid, and ricinoid compounds; complementary acids, and polysaccharides; vitamins, and other organic compounds, in mesoporous materials for application in different industries such as food, agricultural, veterinary, aquacultural, pharmaceutical, cosmetic, cleaning, sanitizing, and disinfection industries, as well as in medicine.
A nanosystem comprising (a) a mesoporous nanocomposite, wherein the nanocomposite comprises (TiO2)-MO, wherein M is a transition metal which is not considered toxic for an environment, mammals, and plants, and (b) one or more natural extracts deposited and/or adsorbed onto the surface and within pores of said mesoporous nanocomposite, wherein the nanocomposite has a surface area from 74 m2/g to 200 m2/g, wherein the concentration of natural extracts is from about 10 mg to 100 mg, and wherein the morphology of the nanosystem is nanospheres of a core-shell structure, wherein the natural extracts are encapsulated by the nanocomposite and gradually released from the nanocomposite.
